Application August 27, 1931, Serial No. 559,787 2 claims. (-01, 12s-241)- The present invention consists of a syringe nozzle especially adapted for use in the treatment of diseases of the vagina and has for an object to provide an expansible dilator head, preferably made of soft rubber, which may be distended to dilate the vaginal walls without inconvenience, discomfort or injury to the patient Other objects of the invention are to provide a dilating head of special construction in order to include the greatest area of soft rubber without increasing the diameter of the nozzle and without decreasing the size of the bore, in order to obtain a maximum amount of dilation and positive rigidity of the dilating head while in an expanded position; to provide a soft rubber dilating head with the tube engaging annulus formed in one end remote from the terminals of the head to project the soft rubber head in advance of the entering end of the nozzle tube to prevent contact of the tube with the patient and to encase medicament-spraying openings formed in the tube to prevent them from being clogged by body secretions or the like; and, to provide a nozzle which includes a tube with a detachablecap onthe entering end thereof, which is provided with only four medicament-spraying openings, offset from thecenter of the cap and disposed at an angularity which insures projection of the medicament at a predetermined angle to augment effective medication.

Additional objects of the invention will be apparent from the'following description of the present preferred form of the invention, taken in con-' nection with the accompanying drawing, where- Fig. 1 is a side elevational view of a nozzle constructed in accordance with the present invention, the fluid discharge tube being 'fragmentarily shown;

The nozzle constructed in accordance with the present invention consists of a main. body or tube 9, preferably made of hard rubber and provided with an axial bore in which an inner or auxiliary tube '10 is slidably mounted, it being preferably made of metal. For convenience in describing the parts of the nozzle, the tube 9 will be hereso: inafterreferred to as the outer tube and the tube 10 as the inner tube. Y

The outer tube is equipped with a longitudinal- 1y adjustable bell-shaped shield 11, which is. adapted to seal the vagina or other orifice into which the nozzle is introduced. The outer periphery' of the tube 10 is tapered, so that when the shield is adjusted to the desired position when inuse, a water-tight seal between the shield and tube is effected. The shield is preferablyar- 7'01 ranged adjacent the outer or entering terminal of the outer tube, soas to lie in proximity to the dilating head hereinafter described. The outer terminal of the outer tube 9 is reduced and tapered, as indicated at 12, and is adapted for'7'5i the reception of a complemental end formed on a dilator head, generally designated 13. The op-' posite orinner end of the outer tube isprovided with a pair of parallel annuli 1'4, Which'are appreciably spaced to provide a finger-receiving zone 15. -The extreme inner end of the outertube is provided with a bayonet none, which is diametrically opposite to a longitudinally extending slot 17, which latter 'opens'through the inner end of the tube. w

The inner tube 10 is greater-in length than the outer tube 9 in order tonormally project both ends of the inner tube beyond the ends of the outer tube, as shown in Fig.2 of the drawing. The inner tube 10 is provided with perforations 18" in the wall thereof, which are arranged in close proximity to the outer or entering end of the tube. The extreme end'of said tube, beyondthe terminal, is provided with screw threads 19, which are adapted for the reception of corre-' sponding threads formed on the bore of a cap 20, the latter being provided with a bore which is coaxial with the bore of the tube 10. The outer end of the cap 20 is formed to provide a circular head in which axial openings 21 are formed. The openings 21 are preferably only four in number and are drilled at an angle of sixty degrees, at a point in the cap which is approximately thirty degrees distant from a line drawn through the longitudinal axis of the cap. It will be noted that the periphery of the cap 20 is provided with an annular recess which tapers inwardly toward the head of the cap and is adapted for the reception of a complementally formed annulus 22 which issues from the inner periphery of the head 13,

adjacent the outer end of the latter. The complemental formation of the annulus 22 not only facilitates assembly of the nozzle head, but additionally, permits easy withdrawal of the nozzle head from its mold in the manufacture thereof. The head of the cap is countersunk in a recess formedin the outer end of the dilator head 13, as illustrated to advantage in Fig. 2. In this way the outer or entering end'of the dilator head prevents contact of the cap head with the patient and also encases the axial openings 21 in the cap head to reduce possibility of the latter becoming clogged by body secretions or the like.

The dilator head 13 is preferably formed of soft rubber and by preference is of cylindrical configuration and of a diameter which conforms to the diameter of the outer tube 9, when said head is in a contracted position. The head is provided with a series of longitudinally extending slots 23 to provide arms or ribs 24, which are adapted to be bowed outwardly when the head is urged into an expanded or dilated position.

Thearms or ribs 24 are relatively thick and are- In order to retain the dilator head in an expanded position, at the option of the user, suitable means is provided. The means employed in the present instance consists of a sleeve 25, which is slidably mounted on the inner end of i the outer tube 9 and is provided with internal threads 26 which are adapted to engage corresponding threads formed on the outer periphery of the inner tube 10.; The sleeve 25 is provided with an inwardly extending lug 27, which is mounted in the slot 17, formed in the outer tube. The sleeve 25 carries a rotatable knurled collar 28, which is provided With 9. detachable pin 29, adapted to extend through an arcuate slot 30, formed in the outer tube 9. Theinner end of the pin 29 is reducedand is mounted in the bayonet slot 16 of the outer tube. The free terminal ofthe sleeve 25 is adapted for engagement with a bulb, tube or the like, used for the introduction of the medicament into the bore of the tube 10.

The shield 11 may be equipped with a suitable Leeaitt discharge duct 31 mounted in a vent opening in the shield. The inner end of the duct projects beyond the inner end of the shield so as to lie within the orifice to intercept fluids being discharged from the latter. It will be noted that the inner end of the duct is appreciably spaced from the outer periphery of the outer tube to provide ample clearancethrough which the fiuids may pass. The outer; end of the duct 31 may be engaged by a carry-off tube 32 or the like.

In use of this device, it isv apparent that the dilator head of the nozzle may be introduced into the orifice in a manner well known in the art, and the shield 11 used to seal the orifice. Dilation of the head 13 ,is efiected by grasping the outer tube 9, preferably in the finger-receiving zone 15, to prevent accidental removal of the nozzle from the orifice. The sleeve 25 may then be operated by the other hand to draw the inner tube inwardly, thereby causing the arms or ribs 24 of the dilator head to be flexed outwardly into then be introduced into the inner tube 10 in a well known manner and operated through the perforations 18 and 21. Ifa liquid medicament is used, it is permitted to discharge through the duct 31 before removalof thenozzle from the orifice. It is apparent that the head may be held in a dilated position by turning the collar 28 to engage either terminal of the head of the bayonet slot 16. .When. it is desired to permit the headto contract, the collar 28 may be rotated until the pin 29 is engaged with'the' .leg of, the bayonet slot, withobvious results. v H

Although I have herein described the 'pre ferred form of retaining a normally contracted nozzle head in a dilated position, by mechanical means, it is nevertheless to beunderstood that mounted on oneof the tubes and e ngaged with the detachable capof the other tube. 1
